The Modbus module MR-Multi I/0 is a compact and rapidly to install solution to connect digital and analog signals from the actor and sensor level directly to a control unit in building automation via Modbus RTU protocol. 29 I/Os, some of them are configurable, are available for different tasks. With strong inductive loads, we recommend protecting the relay contacts with an RC element. The inputs and outputs can be switched and scanned by means of standard registers via a Modbus master. Module address, bit rate and parity are set with two rotary switches on the front or by software. Suitable for decentralized mounting on DIN TH35 rail according to IEC 60715 in electrical distribution cabinets.
